BASIC CONNECTIONS
The basic connections for operating the ADL5601 are shown in
Figure 16. Recommended components are listed in Table 5. The
input and output should be ac-coupled with appropriately sized
capacitors (the device characterization was performed with
0.1 μF capacitors). A 5 V dc bias is supplied to the amplifier
through the bias inductor connected to RFOUT (Pin 3). The
bias voltage should be decoupled using a 1 µF capacitor, a 1.2 nF
capacitor, and a 68 pF capacitor.

SOLDERING INFORMATION AND RECOMMENDED
PCB LAND PATTERN
Figure 17 shows the recommended land pattern for the ADL5601.
To minimize thermal impedance, the exposed paddle on the
package underside, along with Pin 2, should be soldered to a
ground plane. If multiple ground layers exist, they should be
stitched together using vias. For more information on land
pattern design and layout, refer to the AN-772 Application
Note, A Design and Manufacturing Guide for the Lead Frame
Chip Scale Package (LFCSP).
